Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475276, here are decompositions:

67 + 31475209 = 31475276
193 + 31475083 = 31475276
223 + 31475053 = 31475276
277 + 31474999 = 31475276
307 + 31474969 = 31475276
409 + 31474867 = 31475276
499 + 31474777 = 31475276
607 + 31474669 = 31475276

Showing the first eight; more decompositions exist.
